A. Blockchain technology
Background: After the birth of Bitcoin, it was discovered that the technology was very advanced, and blockchain technology was discovered. Bitcoin and blockchain technology were discovered at the same time.
1.1 The purpose of the birth of Bitcoin:
①Currency transactions have records, that is, ledgers;
②The disadvantages of centralized institution accounting - it can be tampered with; Yi Chaofa
Bitcoin solves the first problem: anti-tampering - hash function
1.2 hash function (encryption method)
① Function: convert any A string of length, converted to a fixed-length (sha256) output. The output is also called a hash value.
② Features: It is difficult to find two different x and y such that h(x)=h(y).
③Application: md5 file encryption
1.3 Blockchain
①Definition
Block: Split the general ledger into zones Block storage
Blockchain: On each block, add a block header. It records the hash value of the parent block. By storing the hash value of the parent block in each block, all blocks are connected in order to form a blockchain.
②How does the blockchain prevent transaction records from being tampered with?
After the blockchain is formed, tampering with any transaction will cause the hash value of the transaction block to be different from that of its sub-blocks. , tampering was discovered.
Even if you continue to tamper with the hash value in the sub-block header, the hash value in the sub-block will be different from that in the grandchild block, and the tampering will be discovered.
1.4 The essence of blockchain
①The essence of Bitcoin and blockchain: a big ledger visible to everyone, only recording transactions .
②Core technology: Through cryptographic hash function + data structure, it ensures that the ledger records cannot be tampered with.
③Core function: Create trust. Fiat currency relies on government credibility, and Bitcoin relies on technology.
1.5 How to trade
① To conduct transactions, you need an account number and password, corresponding to the public key and private key
Private key: a string of 256-bit binary numbers , no application is required to obtain it, and you don’t even need a computer. You can generate the private key by tossing a coin 256 times.
The address is converted from the private key. The address cannot reverse the private key.
The address is the identity, which represents the ID in the Bitcoin world.
After an address is generated, it can only be known by everyone if it enters the blockchain ledger.
②Digital signature technology
Signature function sign (Zhang San’s private key, transfer information: Zhang San transfers 10 yuan to Li Si) = signature of this transfer
< p> Verify Korean verify (Zhang San’s address, transfer information: Zhang San transfers 10 yuan to Li Si, signature of this transfer) = TrueZhang San uses his own signature function sign() The private key signs this transaction.
Anyone can verify whether the signature was issued by Zhang San himself who holds Zhang San's private key by verifying the Korean vertify(). It returns true, otherwise it returns false.
sign() and verify() are cryptographically guaranteed not to be cracked. ·
③Complete the transaction
Zhang San will provide the transfer information and signature to the entire network. Under the premise that the account has a balance, after verifying that the signature is true, it will be recorded in the blockchain ledger. Once recorded, Zhang San's account will be reduced by 10 yuan, and Li Si's account will be increased by 10 yuan.
Supports one-to-one, one-to-many, many-to-one, and many-to-many transactions.
In the Bitcoin world, private keys are everything! ! !
1.6 Centralized Accounting
① Advantages of Centralized Accounting:
a. No matter which center keeps accounts, don’t worry too much
< p> b. Centralized accounting, high efficiency②Disadvantages of centralized accounting:
a Denial of service attack
b Stop service after getting tired
p>c Central institutions are vulnerable to attacks. For example, destroying servers and networks, committing self-intrusion, legal termination, government intervention, etc.
All attempts at confidential currencies with centralized institutions in history have failed.
Bitcoin solves the second problem: how to decentralize
1.7 Decentralized accounting
①Decentralization: Everyone can keep accounts. Everyone can keep a complete ledger.
Anyone can download open source programs, participate in the P2P network, monitor transactions sent around the world, become an accounting node, and participate in accounting.
② Decentralized accounting process
After someone initiates a transaction, it is broadcast to the entire network.
Each accounting node continues to monitor and continue transactions across the entire network. After receiving a new transaction, after verifying the accuracy, it is put into the transaction pool and continues to be propagated to other nodes..
Due to network propagation, the transactions of different accounting nodes at the same time are not necessarily the same.
Every 10 minutes, one person is selected from all accounting nodes in a certain way, and his transaction pool is used as the next block and broadcast to the entire network.
Other nodes delete the transactions that have been recorded in their own transaction pool based on the transactions in the latest block, continue accounting, and wait for the next selection.
③ Features of decentralized accounting
A block is generated every 10 minutes, but not all transactions within these 10 minutes can be recorded.
The accounting node that obtains the accounting rights will be rewarded with 50 Bitcoins. After every 210,000 blocks (approximately 4 years), the reward is halved. The total amount is about 21 million, and it is expected to be mined in 2040.
Recording the reward of a block is also the only way to issue Bitcoin.
④ How to allocate accounting rights: POW (proof of work) method
Compete for accounting rights by calculating mathematical problems on several accounting points.
Find a random number that makes the following inequality true:
There is no other solution except traversing the random numbers starting from 0 and trying your luck. The process of solving the problem is also called mining.
Whoever solves the problem correctly first will get the accounting rights.
If a certain accounting node finds the solution first, it will announce it to the entire network. After other nodes verify that it is correct, a new round of calculation will start again after the new block. This method is called POW.
⑤ Difficulty adjustment
The generation time of each block is not exactly 10 minutes
As Bitcoin develops, the computing power of the entire network does not increase.
In order to cope with changes in computing power, the difficulty will be increased or decreased every 2016 blocks (about 2 weeks), so that the average time for each block to be generated is 10 minutes.

B. What kind of problems can blockchain technology solve
Blockchain What kind of problems can technology solve? Blockchain technology can solve the trust problem at a relatively lower cost, which plays an important role in the current emphasis on reducing the burden of the real economy and reducing transaction costs, and has great social value. At the same time, there is still a need for continuous exploration of the blockchain technology itself. It is believed that independent controllable intellectual property rights and patents can be integrated with this technology in the future.
In the future, Jinwowo will focus on promoting the legal circulation and commercial application of big data using blockchain technology.
Jinwowo analyzes the problems that blockchain technology can solve as follows:
The most important thing about blockchain is that it solves the problem of intermediary credit. In the past, it was difficult for two people who did not know and trust each other to achieve collaboration, and they had to rely on a third party.
For example, in payment behavior, any kind of transfer in the past required the existence of an institution such as a bank or Alipay.
However, through blockchain technology, it is the first time that humans have achieved a transfer behavior that both parties can trust without the participation of any intermediary agency. This is a major breakthrough for blockchain.
Analysis by Chongqing Jinwowo: The most important thing about blockchain is that it solves the problem of intermediary credit.
In the past, it was difficult for two people who did not know and trust each other to achieve collaboration, and they had to rely on a third party.
Chongqing Jinwowo analyzes the problems solved by the application of blockchain technology as follows:
The most important thing about blockchain is that it solves the problem of intermediary credit. In the past, two people who did not know and trust each other had to reach an agreement. Collaboration is difficult and requires a third party.
Through blockchain technology, it is possible to complete behaviors in which both parties can trust each other without the participation of any intermediary agency. This is the problem solved by disintermediation (decentralization) in blockchain technology.
Blockchain solves the problem of trust, which is the root of all problems.
WaykiChain is a smart contract platform that supports Turing completeness. WaykiChain adopts the dpos consensus mechanism, with a total of 11 voting nodes, which generate a new block every 10 seconds. Through smart contracts, WaykiChain can realize rich application scenarios such as asset issuance, betting applications, copyright traceability, mutual insurance, decentralized exchanges, and cross-border settlement.
But the most important thing in these scenarios is trust and openness and transparency.
What problems can blockchain technology solve?
Based on mechanisms such as distributed accounting, collective contracts and intelligent consensus, blockchain technology presents information processing characteristics such as decentralization, open sharing, authenticity and reliability, which has triggered increasing attention and attention in the financial field, especially in the Internet financial field. Research applications. There are many blockchain system development companies. Blockchain technology development companies like Renren Chain are relatively reliable. You can refer to blockchain solutions.
Point 1: First of all, you must understand the technical strength of the blockchain technology service provider you choose, including the underlying strength of the blockchain and the technical strength of the team; what successful cases have been developed. Ask for developed projects, and the other party will analyze previous successful cases.
Point 2: It depends on the other party’s existing underlying blockchain architecture and project development experience.
Point 3: You can ask your friends if they know anything about it and recommend it. Personally knowThe one with good comprehensive strength is the Renren blockchain BaaS platform, which can quickly build its own IT infrastructure and blockchain services on the open cloud platform. Of course there are others, choose the platform that suits your business. There are still issues that need attention that have not been mentioned, and I hope others can help add them~
The blockchain is similar to a "public ledger". Each block is a "ledger page". When people conduct transactions on the blockchain, the transaction data will be disclosed to every node in the blockchain, and It is recorded on the "ledger page", permanently stored, and cannot be tampered with. In view of the decentralization, openness and non-tampering characteristics of the blockchain, each work entered into the blockchain copyright registration system will generate a unique digital fingerprint that cannot be tampered with.
Users only need to pass the Xiaoxi Copyright Chain platform identity authentication authorization, and after successfully authenticating "I am me", submit the work to the Copyright Chain. After the background review is passed, the data will be generated and written into the blockchain to generate a certificate. To apply for a paper certificate from the Copyright Protection Center, you need to click "Copyright Certificate Application", then follow the steps to fill in the information, pay the fee, and wait for review... From this point of view, the blockchain + copyright model is really safe, time-saving, and effort-saving.
When it comes to legal protection, we have to mention "infringed" copyright as an intangible asset. If the creator lacks awareness of rights protection, the work may face infringement. Xiaoxi Copyright Chain does this relatively well in the industry. The reason why this platform has become the first smart rights protection platform based on blockchain in China is also inseparable from the support of the Chongqing Notary Office. The digital document storage technology based on the blockchain has been recognized by the notary office and can ensure that the content of the notarization application cannot be tampered with, providing help for the digitization, networking, and informatization of notary services. Notarization parties can submit "preservation evidence" for notarization online through the Xiaoxi platform, making the rights holder's ownership of the work more judicially effective, effectively facing infringement, and improving risk response capabilities.
Blockchain, a new credit evaluation system, provides new technical support for the service reform of notary offices. Xiaoxi Copyright Chain has moved part of the business of the Chongqing Notary Office onto the blockchain platform, which can be called an innovation of blockchain in the field of notarial certificate business. In the process of notarization, material review and verification is the most critical and important part. The process design of the "blockchain + notarization" background changes the previous steps that required manual verification in various departments. Notaries only need to review the materials provided by users online to quickly complete the review and verification work, which greatly improves work efficiency.
The distributed architecture and non-tampering characteristics of blockchain technology can help solve problems such as the authenticity of bills and opaque information. When parties need to verify whether a note has been tampered with or transferred, the blockchain can provide indisputable proof of consistency.
Digital currency also takes advantage of this feature of blockchain. Puyin is a tea-based digital currency developed based on blockchain technology..
Analysis of Chongqing Jinwowo:
First, through its application in the field of digital currency, blockchain provides a solution for the flow of capital flow (or capital flow) information on the Internet.
Secondly, the blockchain solves the problem of confirmation of authority during the transaction process through encryption and reference to distributed ledgers.
Thirdly, the blockchain determines the exchange of digital assets through the technology of consensus mechanism.
C. What are the applications of blockchain technology?
Developing Ethereum Cat based on Ethereum, this is not considered an application, it is a bit interesting, and there is also NetEase Planet. For traceability, I have snapped up the Orange Chain made by China Enterprise Tongbao Blockchain, which is used for blockchain traceability records on Orange.
D. Bitcoin doubled in February, “blockchain + finance” is booming, what should you do to have a chance
Undoubtedly, Bitcoin If it were a gold mine, the blockchain would be the cart that transports the gold. A few years ago, people only paid attention to the gold mine itself, but later it was discovered that the more valuable thing was this small cart. In addition to loading the gold mine, it could also hold many other things, such as equity, debt, and accounts. …This is the future, the future is already here, it’s just not popular yet.
So, Xiao Haozi wants to say that young people who are interested in blockchain + finance should live in the future and make what is missing. Don’t create concepts and make quick money, and play with technology. The new heights of finance, your future, is truly a sea of stars.

E. What is blockchain development and can it solve any problems_Problems about blockchain
In a narrow sense, blockchain is a kind of data area in chronological order. Blocks are sequentially connected to form a chain-like data structure that can be modified and cryptographically guaranteed to be an untamperable and unforgeable distributed ledger (distributed database).
Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed hidden hole node consensus algorithms to generate and update data, and uses cryptography to ensure data. Security of transmission and access, a new distributed infrastructure and computing paradigm that utilizes smart contracts composed of automated script code to program and manipulate data.
Can solve the following problems for enterprises:
Evidence storage and collection
Use Renren BaaS to quickly enter business data into the chain, save it permanently, and cannot be tampered with by any person or institution.
Digital assets
No development is required. A variety of digital assets can be quickly created through the management backend, which can be used in many fields such as finance and points exchange
Anti-counterfeiting traceability< /p>
Based on Renren Chain BaaS, create an ID for each product, widely used in e-commerce, food and drug safety, trade and other fields
Supply chain
It is very convenient to add management nodes, effectively improving the supply chain Improve management and operational efficiency and reduce costs
F. What kind of technology is "blockchain"
What kind of technology is "blockchain" Blockchain It is an important concept of Bitcoin. The "2014-2016 Global Bitcoin Development Research Report" released by Huobi, Tsinghua University PBC School of Finance Internet Finance Laboratory and Sina Technology mentioned that blockchain is the underlying technology of Bitcoin. and infrastructure. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block. .
In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-forgeable. Account book. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and utilizes automated Smart contracts are composed of scripts that program and compute data in a new decentralized infrastructure and normalize computing.
Domestic blockchain application platforms include an asset custody system based on blockchain technology jointly developed by the digital currency crowdfunding platform Biying China, China Post and IBM.
Blockchain is a decentralized, distributed ledger system participated by nodes. The data stored on it cannot be forged or tampered with, and is open to the public. Transparent, the information and value recorded by each account at any point in history can be found on the blockchain. The characteristics of the blockchain protocol provide the necessary foundation for the execution of smart contracts. The contract can be automatically executed and trusted according to established conditions without the need for auditing by any centralized organization.
Blockchain technology is the underlying core of the Bitcoin system. Its essence is a decentralized ledger. When people conduct transactions through the Internet, a new transaction will be recorded on the ledger, and this ledger is A decentralized ledger is jointly maintained by everyone on the network. People can see ongoing transactions at the same time, and control is not in the hands of institutions or individuals. Transactions cannot be tampered with or forged, and they will be permanently stored in the ledger.
For example, the Tongxin Huzhu blockchain mutual aid platform has four major characteristics in applying blockchain technology:
Openness and transparency
Openness and transparency, once all information recorded on the blockchain is recorded, it will be very Difficult to tamper, unable toHidden, users can view it at any time.
Democratic decision-making
Bottom-up decision-making, the blockchain proposes a variety of different consensus mechanisms to help users effectively form bottom-up decisions and jointly participate in major decisions.
Accurate execution of rules
Accurate execution of rules. The smart contract technology defined on the blockchain converts all rules into public and clear codes, which can be executed accurately and accurately. Once anyone is identified Cannot intervene.
Never downtime
Never downtime, the blockchain based on the public chain is not affected by any organization or individual. As long as the incentive mechanism is effective and the Internet exists, the blockchain will exist.
What is blockchain? Blockchain is a decentralized shared accounting technology that allows all parties involved to establish a trusting relationship at the technical level. Blockchain can be roughly divided into two levels: one is the underlying technology of the blockchain; the other is the upper-layer application of the blockchain, that is, the transformation, optimization or innovative application based on the blockchain. Blockchain is still in its infancy. Many people have discussed with me how we can ensure both rights and privacy at the same time. Of course, we are just exploring now. We need fair content across the entire network and clear protection. This is what I can only say. So far, this is my arrangement for the future.
Blockchain concept? The idea of blockchain is to be completely decentralized and rely on decentralized justice. In that case, theoretically the cost will drop a lot, proving that real assets and property rights can directly correspond to each other on the Internet. It has solved the problems of decentralization and asset ownership that were not solved by the first generation of Internet information. How big a role does big data play in financial innovation now? Only by registering big data can we know who it belongs to. In fact, this has always been a problem that we cannot solve now. This is not a small problem. If there is a technology in the capital market that makes the property rights of things that were originally unclear clear, that will be a big problem for us. The entire market is undergoing a huge transformation.
What is blockchain? Blockchain technology itself can solve data ownership, pricing and sharing mechanisms. This still cannot completely solve certain problems. To give a simple example when it comes to user privacy, I have a piece of data placed on the machine. The partner comes over and makes an insurance analysis to analyze the cooperation. There is a risk here. Or not, can we deal with it or clarify the property rights of the laboratory, and then clarify the processing rights and data rights. The common products produced by everyone are common to everyone. If we need to divide different things, how to price them and how to divide them? In addition to the technology of blockchain and a decentralized database, when it comes to the above mentioned tasks, it is another issue, and then there is the issue of pricing and the market mechanism. All fields have proven to recognize this rule, so this I think blockchain is a very good core technology, but it cannot cover all problems.
Introduction to Bubi Blockchain
The positioning of Bubi Blockchain is mainly to provide commercial-grade blockchain infrastructure services, which mainly includes building a blockchain system and building a support system with high scalability on top of the blockchain system. On top of this support system are applications from all walks of life. Bubi focuses more on the underlying technology of the blockchain. In the past three years or so, a team of more than a dozen people has devoted almost all their energy to the research and development of the underlying technology. The reason why Bubi Blockchain chooses points has something to do with the market's promotion method. As we all know, blockchain is a technology that is very suitable for the issuance and trading of digital assets. Points are a digital asset that is naturally legal and compliant, and has a small impact because of its small amount. Therefore, it is a very suitable choice to use points as your first attempt at digital asset issuance. Issuing points based on the blockchain can indeed bring great help to the circulation and mutual exchange of points.
What is blockchain? The application of blockchain technology in the field of property transfer is only one aspect. In addition to reducing property transfer costs, blockchain technology can also be applied to various fields involving company stocks, financial derivatives, and points programs of commercial institutions. The blockchain community is currently focusing on promoting the wider application of this technology in the field of financial assets. Relatedly, various platforms that are still under development have also received very considerable investment.
Blockchain concept? Structurally or by definition, these things are very different. The U.S. dollar, or any currency, from a typical definition, is primarily used as a medium of exchange or store of value for economic activities. Within the geographical scope where a certain currency circulates, people in the region reach a consensus on the use of this currency, making it convenient for everyone to use the same currency to purchase goods or services (the function of currency as a medium of exchange). There is a responsibility to manage the currency through monetary policy in order to ensure the preservation of the value of the currency and avoid the occurrence of inflation (the store of value function of currency). In today's world, almost everyone uses some form of currency in their daily lives.
What is blockchain? Even developers within the blockchain community often easily overlook the big picture mentioned above. There are many competitive projects in the blockchain community, and they are also full of various disputes about the evolution direction of blockchain technology. Over time, some projects in the community will be successful, and others will not be so lucky. Things will not always develop in the direction we expect, but no matter how these projects in the early blockchain community develop, one thing is very clear, that is, blockchain technology has brought us at least A revolutionary function: Blockchain technology will greatly reduce the cost of financial property transfer, and blockchain will be used to control, manage and transmit financial property.
What is blockchain? Blockchain concept? After a certain application analysis, we return to the starting point. The definition of this blockchain technology will surely become more and more abundant with the expansion of applications, and people will discover more mysteries of blockchain technology.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block. .
The blockchain is public on the Internet and can be queried in every offline Bitcoin wallet information. The functionality of a Bitcoin wallet relies on confirmation with the blockchain, and a valid check is called a confirmation. Usually a transaction requires several confirmations before it can proceed. The lightweight Bitcoin wallet uses online confirmation, which means it does not download the blockchain data to the device storage.
Many of Bitcoin’s altcoins also use the same design, but are slightly different in proof of work and algorithm. For example, using proof of stake and SCrypt, etc.
Blockchain timestamp service and proof of existence
This concept was proposed in Satoshi Nakamoto’s white paper [1], who created the first block, the “genesis block”.
On January 3, 2009, Satoshi Nakamoto, the founder of Bitcoin, left an unchangeable sentence in the genesis block:
“The Times 03/Jan/2009 Chancellor on brink of second lout for banks (on January 3, 2009, the chancellor was on the verge of implementing a second round of bank bailout)."
It was then that the British chancellor Darling was forced to consider a second bailout of the banks. In a time of crisis, this sentence was the headline of a front-page article in The Times that day.
With the blockchain’s timestamp service and proof of existence, the time when the first blockchain was created and the events that were happening at that time are permanently retained.
The Bitcoin company BTCC launched a service "Millennium Chain" in 2015, which is a blockchain engraving service, which uses the above principles. Users can engrave text on the blockchain through this service and store it permanently.
Bitcoin, Litecoin, Ruitai Coin, and Qianjin Card are all digital currencies based on blockchain technology.
Chongqing Jinwowo analyzed: Blockchain is actually a decentralized distributed ledger database.
How popular is blockchain technology?
Blockchain technology makes DAC possible. DAC is something that can fundamentally subvert the organizational model of human society. I believe that its impact on society will surpass the Industrial Revolution and become the most profound change that the Internet has brought to the world.
The essence of blockchain technology is a decentralized and decentralized structure of data storage, transmission and certification methods, which is replaced by data blocks (Block)It eliminates the current Internet's reliance on central servers, allowing all data changes or transaction projects to be recorded on a cloud system, theoretically achieving self-certification of data during data transmission.
Blockchain technology can be applied to many industries:
Art industry
Ascribe allows artists to use blockchain technology to declare ownership, Issue numberable, 100% editions of your work in digital form for any type of artwork. It even includes a marketplace where artists can buy and sell through their website without the need for any intermediary services.
Legal Industry
BitProof is the most advanced of the many document timestamp applications that have emerged in recent years, and will make traditional notarization methods a thing of the past. Compared with free versions including Blocksgin and OriginStaemp, BitProof provides more services, including one for intellectual property rights. Interestingly, BitProof recently collaborated with a San Francisco IT school to put all their students’ academic certificates on the blockchain, completely redefining how diplomas and student certificates are processed and used.
Development Industry
Colu is the first company to allow other companies to issue digital assets. They can "tokenize" various assets and have a profound impact on many people. Although the free Bitcoin wallet Counerparty also allows simple tokens to be issued and traded among other wallet holders, Colu tokens can be configured in various states and types, and can leave and return to the system. , and when storing data on the blockchain is too large, the data can be stored on the BitTorrent network.
Internet Mutual Aid Industry
Tongxin Mutual Aid is the first blockchain online mutual aid platform to be implemented and applied. Technically, through blockchain and big data technology, it eliminates the shortcomings of the traditional online mutual aid model. Establish an open and transparent new online mutual aid platform.
Aite Cat is a virtual pet game produced under blockchain technology. This virtual cat is similar to Internet Letts Dog, 360 pet cat, and NetEase’s Planet are all the same type of blockchain virtual products. The difference between Aite Cat is that the entire cat design uses a 3D three-dimensional effect, making the cat’s The display is no longer a single picture, allowing the cat to move, which increases the fun of the cat.
What technology is the Huangbao blockchain system?The Huangbao blockchain is a powerful decentralized loop intelligence system. The Huangchain chain is referred to as HUANG. It is the first to be used in financial services, advertising media, games and entertainment, various life applications and other fields, becoming a blockchain 3.0 The representative virtual currency of the era, media chain 3.0 technology has safer, more efficient,The core characteristics of more flexibility and openness, and the widespread application of its technology, will surely trigger new forms and new ideas in the global media industry, and create convenient services and new concepts. This marks a new economic era for the public. before.
G. What accounting problems do you think blockchain technology can solve
Blockchain distributed databases can be practically applied in corporate accounting information systems.
The blockchain distributed database is like a public ledger, which should naturally be able to record corporate accounting information.
Any information that needs to be saved can be written to the blockchain and read from it, so it is a database.
A shared, distributed database technology or intelligent peer-to-peer network that can identify, disseminate and record information through a distributed database.
H. What is blockchain technology and how it changes business and financial models
Blockchain technology is a distributed ledger technology that Allows multiple participants to jointly maintain a secure, transparent and immutable record on a decentralized network. Blockchain technology was originally designed for the digital currency Bitcoin, but is now widely used in many other fields.
The core features of blockchain technology include:
Decentralization: Blockchain has no central control agency, and data is distributed on various nodes in the network, which makes it decentralized. The centralization feature reduces the risk of single points of failure.
Transparency: Transaction records on the blockchain are public to all participants, and anyone can view these records. This helps increase trust and reduce the risk of fraud.
Immutable: Once a transaction is recorded on the blockchain, it cannot be easily modified or deleted. This guarantees data integrity and security.
Smart contracts: Transactions on the blockchain can be automatically executed to implement "smart contracts", which automatically execute corresponding operations when specific conditions are met. This helps simplify complex business processes and reduce costs.
Blockchain technology has had a profound impact on business and financial models, which is mainly reflected in the following aspects:
Reducing costs: Blockchain technology can reduce intermediary links and reduce costs. Transaction costs and operating costs. For example, by adopting blockchain for cross-border payments, remittance fees can be significantly reduced.
Improving efficiency: The automation and smart contract features of blockchain technology help improve the efficiency of business processes, reduce manual intervention, and reduce error rates.
Enhance trust: The transparency and non-tamperability of blockchain technology help to establish a reliable trust system, reduce the risk of fraud, and provide better protection for commercial activities.
Innovative business models: Blockchain technology has spawned many new business models, such as decentralized finance (DeFi), digital asset trading, supply chain finance, etc. These new business models bring new opportunities to existing industriesDisruptive changes are coming.
In short, blockchain technology, as an emerging technical means, is gradually changing the landscape of business and finance. With the continuous development of technology and the in-depth promotion of applications, blockchain is expected to have a more extensive and far-reaching impact in the future
